Physical properties: 47kg/mm22. Magnesium-aluminium right-angle ruler elongation: 17%3. Magnesium-aluminium right-angle ruler bending point: 110kg/mm24. Vickers Strength of Magnesium-Aluminum Right-Angle Ruler: HV80Magnesium-aluminium right-angle ruler has the following advantages: 1. Light weight, easy to use and easy to move. 2. It is not easy to deform. The bending point of general steel material is 30kg/mm2, and that of general cast iron is 38kg/mm2. The bending point of this material is 110kg/mm2, and the bending resistance index is far beyond other materials. 3. Easy to keep, suspension and leveling can be done without affecting its straightness and parallelism due to long-term leveling. 4. It is not easy to show off, do not use oil during use, do not use it for a long time, gently coat a thin layer of general industrial oil when stored.size ;400*400 500*500 600*600 800*800 1000*1000package picture
